“With two young players in Joe Powell and Ryan Lonergan in that area we felt the need to bring in a more mature option, an older head who can provide some game experience and help the progression of our young talent.”

Roos said he was excited to link up with the franchise.

“I am delighted to be joining the Brumbies and look forward to helping the team achieve their goals in 2017,” Roos said.

“It is fantastic to get a chance to be a part of such a well-renowned organisation.

Larkham said Cubelli would be aiming to return to the Pumas setup for the June Test window, before hopefully resuming his Brumbies duties in the back end of the Super Rugby season.

The Brumbies face another blow on the injury front, with Scott Sio ‘highly unlikely’ to line up with the team in Friday night’s clash with the Crusaders.

“Highly unlikely that he'll be right for this first round but he's tracking nicely so we'll make a bit of a decision on that this afternoon,” he said.
